What makes Onix so well suited for radiant heat and snow melting applications?

Cross-linked Durel EPDM is extruded into a tube and wrapped with an AlumaShield barrier and a second layer of EPDM. This composite tube is reinforced with 1000 denier aramid cord, the same incredibly tough and heat resistant material used to make fire and bullet proof shields. A final outer jacket of EPDM is applied. The result is a durable, flexible tubing formed of five heat and age resistant materials, proven in tens of thousands of installations over the years.

One of the best features of Onix tubing is its aluminum barrier layer, AlumaShield™. Unlike plastic barriers, AlumaShield is unaffected by sunlight, UV radiation from fluorescent lamps, moisture, or elevated temperatures. Due to its placement inside the tube, the AlumaShield barrier can't be scraped off or damaged by typical job site abuse.
